I made a couple of these for an alternate version of a countdown timer in the app that I'm currently working on. This is my first foray into Sketch, and I've been extremely grateful for the resources that currently are available to Sketch users, so here's my small contribution. The numbers are in Geogrotesque (designed by Eduardo Manso), which I picked for this resource and app because of the its geometric feel, which is softened and made very 'consumer-friendly' because of it's rounded finish. You can easily swap these numbers out for any other type, though! Enjoy :)
